Description
Read from Model Specific Registers (logMSRs enabled):
MSR_PKGC3_IRTL
MSR_PKGC6_IRTL
MSR_PKG_C2_RESIDENCY
will cause a general protection exception and instant reboot.
So, if you have Xeon X5670 (or same gen) - just comment out this lines:
IOLOG("MSR_PKGC3_IRTL...................(0x60a) : 0x%llX\n", (unsigned long long)rdmsr64(MSR_PKGC3_IRTL));
IOLOG("MSR_PKGC6_IRTL...................(0x60b) : 0x%llX\n", (unsigned long long)rdmsr64(MSR_PKGC6_IRTL));
IOLOG("MSR_PKG_C2_RESIDENCY.............(0x60d) : 0x%llX\n", (unsigned long long)rdmsr64(MSR_PKG_C2_RESIDENCY));
